The RA2 is available both manually and electrically operated using a tubular motor inside the barrel. The options priced are shown on your quotation which also shows the method of operation we have included. This list shows possible options which would incur different costs.
SWIVEL BELT WINDER - for shutters up to 15kg
This type of operation is used when the roller shutter is fitted on
the outside of the property and is lowered/raised using the
Swivel Belt Winder from the inside. The grey belt is pulled up
and down to lower and raise the shutter. The swivel winder
coils the belt when it is pulled to open the shutter. The belt is
14mm wide and grey in colour and a guide tube to protect the
belt through the building wall. The shutter locks by using the
locking spring which connects the curtain to the barrel
and lock out in the back of the shutter box.
GEARED BELT WINDER - for shutters between 15kg and 25kg
This is the same as the Swivel Belt Winder but uses a crank
handle to raise and lower the shutter. The Geared Winder
works at 1:3 ratio with removable handle. The shutter locks by
using the locking spring which connect the curtain to the barrel and
lock out in the back of the shutter box.
ROD CRANK OPERATION - for shutters up to 25kg
This type of operation is usually on windows where the shutter
is external and is operated internally using a geared rod crank
handle which hangs vertically and secures into a clip when
not in use. The shutter is lowered and raised by turning the
handle in a clockwise or anti clockwise direction. The shutter
locks by using the locking spring which connect the curtain to
the barrel and lock out in the back of the shutter box.
Roller Shutters usually installed mainly over doorways or
Serveries are raised up and down by lifting and lowering the
curtain by hand. The roller shutter has a spring in the barrel
which helps lifting the shutter. As standard a central bottom
lath lock is provided which has a key in the bottom lath and
bolts shoot into the guides rails at each side. The Bottom
lath lock can be operated from both sides but has a secure
and non-secure side to the lock. Optional bullet locks are
available which are pins that go through the guide rails each side.
ELECTRIC - (N.B. minimum shutter width 750mm)
Electric shutters are usually fitted on larger openings where
Manual Operation is not suitable or where the operator
requires an easy, clean and user friendly type of operation.
Single phase tubular motors are enclosed within the barrel
giving full protection from the elements. Electric Roller
Shutters can be controlled individually or grouped to one
controller. The controllers available include internal rocker
switch, security key switch or Remote Control. Manual
overrides are available on Electric Roller Shutters which
allow the shutter to be operated when the power to the
shutter has failed.
